CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority under 35 U.S.C. §119 to Chinese Patent Application No. 201210175201.6, filed on May 30, 2012, titled “BRAINSTORMING IN A CLOUD ENVIRONMENT”, which is incorporated herein by reference in its entirety.

BACKGROUND

With respect to product innovation or daily management, brainstorming activities are becoming more and more important. Brainstorming may be considered a group or individual creativity technique by which efforts are made to find a conclusion for a specific problem by gathering a list of ideas contributed by its members. Although there are various types of specific techniques, in conventional brainstorming sessions, most people use sticky notes and a white board as tools to facilitate the collection and organization of ideas for a particular topic. In one example, the topic may be ideas to work more efficiently. As such, one or more members of the brainstorming session may contribute ideas (e.g., PowerPoint presentations, time lines, additional meeting rooms, etc.), which are written down on sticky notes, and then arranged into clusters (categories) on the white board. However, such mechanisms are inefficient and are limited to people in the same location having a large white board with sticky notes. Further, the ideas presented on the white board are typically not organized in a consistent manner, and it is relatively subjective and difficult to classify the ideas in an organized manner. Also, such a conventional mechanism makes it nearly impossible to have more than one version of the clusters, and require additional time for generating a summary for the brainstorming session. Further, such brainstorming sessions are typically not shared with different teams.

DETAILED DESCRIPTION

Embodiments provide a cloud-based service for brainstorming, which allows people in different locations having access to the web or mobile device to participate in live brainstorming sessions. Among other features, the cloud brainstorming service provides an automatic clustering mechanism which automatically groups similar ideas, thereby allowing the host and participants to be more focused on the creation of ideas themselves, as opposed to organizing the submitted ideas, which may be relatively difficult if the brainstorming session includes a large number of participants. Further, the embodiments encompass the use of an in-memory database system, which permits the cluster results to be provided to the participants in real-time or near real-time. Further, the user has the option of adjusting the cluster results manually (e.g., adding a new cluster, changing a name of the cluster, adjusting the ideas among the plurality of clusters, creating a new idea, and combining duplicate ideas). Also, the cloud brainstorming service may encompasses a social share component, which allows users to view brainstorming sessions (e.g., topics, ideas) conducted by other groups or team members. The similar topics may be grouped together as well as similar ideas within each topic so that a user may easily browse brainstorming sessions, thereby reducing duplicate efforts.

According to one aspect, the cloud brainstorming service may provide a new brainstorming template over a network to a host of a brainstorming session after the host logs into the system and selects a new brainstorming session option. Then, the host is able to enter brainstorming settings such as the period of time when the brainstorming session is active, the participants (or members), a brief description of the session, and one or more topics for which ideas are solicited. Upon receiving the brainstorming settings, the cloud brainstorming service may provide an idea submission page to each of the participants. During the time period identified by the brainstorming settings, each participant may enter and submit his/her ideas for each identified topic, and the cloud brainstorming service is configured to de-duplicate redundant ideas, arrange the submitted ideas into one or more clusters (e.g., categories) and provide the clustered ideas over the network in real-time as each user submits his/her ideas. Although the participants are located in different locations, the clustered results may be displayed via a user interface that is common to each of the members so that each participant can view the submitted results as the ideas are populated. The ideas and clustered results may be stored in the in-memory database system, which allows for relatively quick processing and retrieval. These and other features are further explained with reference to the figures.

FIG. 1 illustrates a system 100 for providing a cloud brainstorming service according to an embodiment. The system 100 may include a plurality of user devices 102, as shown in the user interface (UI) layer. A user may operate the device 102-1 or the device 102-1 to log into the system 100, and create/join a brainstorming session. The UI layer may be developed by Hyper Text Markup Language 5 (e.g., HTML5), and may be configured to operate in different types of browsers and platforms.

By way of non-limiting example, then, the devices 102 may include a laptop or desktop computer, a netbook, a tablet computer, a smartphone, a camera, or any device capable of accessing a network. As known, the devices 102 may include an application executing on an operating system such as the application illustrated with respect to device 102-1 and/or a web browser illustrated with respect to device 102-2. The application/web browser may include functionality that permits the devices 102 to communicate with the brainstorming cloud service located on application server 104. In this regard, the term “cloud” or “cloud-aware” references the use of “cloud computing,” which, generally speaking, includes a style of computing in which computing resources such as application programs and file storage are remotely provided over a network such as the Internet, typically through the web browser. For example, many web browsers are capable of running applications, which can themselves be application programming interfaces (“API's”) to more sophisticated applications running on remote servers. In the cloud computing paradigm, a web browser interfaces with and controls an application program that is running on a remote server. Through the browser, the user can create, edit, save and delete files on the remote server (e.g., the application server 104) via the remote application program. Thus, it may be observed that the application server 104 and the devices 102 may also represent examples of cloud computing. The application associated with device 102-1 may be virtually any type of application capable of running on an operating system, and the web browser associated with device 102-2 may be any type of web browser known in the art.

Although only two devices 102 are illustrated in FIG. 1, the embodiments encompass any number of devices 102, thereby having a plurality of users who may be participants in the brainstorming session. Each device 102 may communicate with the application server 104 (in the middle layer) via a network. The network may be the public Internet or other wide area public or private network such as a corporate or other intranet, and/or a smaller-scale, local or personal network, any of which may be implemented using standard network technology.

In the middle layer, the application server 104 hosts the cloud brainstorming service. For example, the application server 104 may include an Application Programming Interface (API) 106, a session management unit 108, a user management unit 110, a security management unit 112, a message service component 114, a brainstorming logic component 116, a data management component 122, a software frame work 126, a clustering component 124 (e.g., the clustering component may be implemented in a distributed solution having a software framework 126), a node cluster 118, and a load balancer 120. The application server 104 may include other components that are well known to one of ordinary skill in the art. The application server 104 may communicate with the devices 102 via the API 106 (through the use of the message service component 114) and the application server 104 may communicate with the database layer via the data management component 122.

For example, the API 106 may represent the backend functional API(s) being exposed as a RESTful API, which is a web service implemented using Hypertext Transfer Protocol (HTTP) and principles of Representational state transfer (REST). The API 106 may permit communications between the application server 104 and each device 102. The data management component 122 manages all data operations which communicate with the database layer, which includes an in-memory database system with multi-tenancy 126. All of the data captured in the cloud brainstorming service may be stored in the in-memory multi-tenancy database system 126.

The in-memory multi-tenancy database system 126 may include a plurality of index servers 128 and one or more in-memory database systems 130. The in-memory database system 130 may be a type of database system that supports real-time analytics and transactional processing. For example, the in-memory database systems 130 may include a parallel processing data store that utilizes row-based, column-based, and/or object-based storage techniques. In one embodiment, the in-memory database systems 130 may be HANA Enterprise 1.0 (any other versions) that is developed by SAP.

The in-memory database systems 130 may be equipped with multi-tenancy mechanisms, thereby transforming the database system into the multi-tenancy in-memory database system 126. For example, each index server 128 may be associated with a different customer or tenant. In particular, a customer may be an enterprise such as a company, and the company may utilize the cloud brainstorming service provided by the application server 104 for facilitating brainstorming sessions within the company. Therefore, the company is associated with a dedicated index server that allows the brainstorming data of that company to be stored in the in-memory database system 130 in such a manner that the company's brainstorming data is separate from brainstorming data of other tenants or companies. As such, each index server 128 may be associated with its own storage volumes, transaction domain and virtual memory. Therefore, the data operating in each tenant environment would not affect the data stored in other tenant environments. Although FIG. 1 illustrates six index servers (e.g., first index server 128-1, second index server 128-2, third index server 128-3, fourth index server 128-4, fifth index server 128-5 and sixth index server 128-6), the embodiments encompass any number of index servers.

The session management unit 108 may be configured to manage the brainstorming session when a user logs into the system (e.g., entering a login ID, password combination). The session management unit 108 may generate a brainstorming session that includes the user's login information such as user's login name, password, as well as other basic information, and any relevant authorizations. Also, the session management unit 108 may track user activities in the system 100 such as if the brainstorming session is not authenticated or the session has expired, as well as the brainstorming session time period.

The user management unit 110 may be configured to manage user information, user registrations, user authorization settings, and any type of user hierarchy settings. The user management unit 110 may be employed as a multi-tenancy system having a plurality of separate databases that stores each of the various types of user information. Also, the user management unit 110 may be configured to register each user and/or device 102 who may wish to use the cloud brainstorming service, and to store identification information from such users within its database. For example, the user management unit 110 may provide a registration page over network in order to allow a particular user register with the cloud brainstorming service. Upon entering the relevant information, the user management unit 110 may register the user based on the registration information received over the network from the user and store the identification information along with any other type of user information within its database. However, there are many example scenarios and techniques by wish user and/or devices 102 may come to be registered with the cloud brainstorming service through the user management 110. The security management unit 112 may be configured to cooperate with the session management unit 108 and the user management unit 110 to handle all security check rules and authorizations checks.

The message service component 114 may be configured to manage all exchanged messages between the devices 102 and the application server 104. For instance, the message service component 114 may be configured to coordinate all messages from the host to the participants (and vice versa), as well as update the brainstorming session pages in a real-time or near real-time manner so that each of the participants have relatively immediate access to the progress of the brainstorming session. For example, brainstorming is a team activity and involves one host and many other participants. In some cases, the participants may be in different locations and cannot communicate with each other face to face. As such, the message service component 114 may synchronize all the information and operations between the devices 102 such that the participants can share the same screen and stand in the same page for better understanding and communication.

For example, when a user (the host) wishes to create a new brainstorming session, the message service component 114 may provide, over the network, a new brainstorming session template to the host of the brainstorming session. The new brainstorming session template may provide brainstorming settings for selection by the host. For example, the brainstorming settings may include the subject of the brainstorming session, the participants, the time period, a brief description of the brainstorming session, and one or more topics to be discussed in which ideas are solicited from the identified members. The new brainstorming session template is further described later in the disclosure with respect to FIG. 7.

Thereafter, the message service component 114 may receive the new brainstorming information over the network from the host, and provide an idea submission page to the identified participants. For example, the idea submission page permits each participant to enter his/her ideas for each of the topics identified by the host in the new brainstorming session template. The idea submission page is further described later in the disclosure with respect to FIG. 8. When a particular user submits his/her ideas, the brainstorming logic component 116 and/or the clustering component 124 may perform one or more processes on the submitted ideas such as de-duplicating ideas and arranging the ideas into clusters (as further explained below), and the message service component 114 may provide the de-duplicated ideas (or processed ideas) that are arranged into the clusters, over the network, to the particular participant. Thereafter, after each participant submits his/her ideas, the same process is repeated, and the message service component 114 automatically updates the results for each of the participants.

More generally, the message service component 114 provides interactions among the cloud brainstorming service, the host and each of the other participants such that the participants can collaborate on the ideas and topics during the brainstorming meeting and can see each other participants' ideas as well as the clustering results immediately via the message service component 114. To realize this, the embodiments encompass a HTTP/HTTPS protocol. The HTTP/HTTPS protocol may permit the passage of messages through most proxies and firewalls such that the brainstorming session will not be affected by the network topology. Also, the embodiments encompass the use of Comet technology based on HTTP/HTTPS in order to permit the devices 102 to receive push notifications about the others' operations. As a result, the users of the devices 102 do not need to refresh the display screen (time by time time) to view the updated results. In addition, each of the participants may be able to vote for the top ideas for a particular topic. Therefore, the message service component 114 may also provide the voting results immediately for display as the voting information is received from each of the participants using the same mechanisms.

The brainstorming logic component 116 may be configured to handle the core logic of the system 100 such as data collecting, duplication check, social share and/or manual adjustment of the clusters. The details of the brainstorming logic component 116 are further illustrated in FIG. 2, which is explained later in the disclosure.

The clustering component 124 may be configured to retrieve the submitted ideas (which may have already been de-duplicated) from the in-memory database system 130 and arrange the submitted ideas into one or more clusters, where each cluster is a group of similar ideas. For example, for a particular brainstorming topic such as “working efficiently,” the submitted ideas may include face-to-face conversion (as opposed to teleconferences), no overtime meetings, less PowerPoint presentations, more meeting rooms, faster and more stable network, second large LED screen, headset for phone, increases in salary, timeliness, and using cloud brainstorming service, for example. The clustering component 124 may be configured to automatically arrange these ideas into one or more clusters or categories. In one example, the clusters may be “communication,” “facility” and “miscellaneous.” As such, the clustering component 124 may arrange the following ideas into the “communication” cluster: face-to-face conversion, no overtime meetings, and less PowerPoint presentations, for example. Also, the clustering component 124 may arrange the following ideas into the “facility” cluster: more meeting rooms, faster and more stable network, second large LED screen and headset for phone, for example. Further, the clustering component 124 may arrange the following ideas into the “miscellaneous” cluster: increases in salary, timeliness, and use of cloud brainstorming service, for example. Not only may the clustering component 124 arranged the submitted ideas into one or more clusters, but also the clustering component 124 may determine the name associated with each cluster (e.g., communication, facility, and miscellaneous). In one embodiment, the clustering component 124 may use support vector classification to implement the clustering mechanism. The clustering component 124 may utilize a vector model based on training data in order to parse the sentence of the idea and automatically assign it to the appropriate category, which is further explained below.

Because the clustering component 124 may consume a relatively large amount of resources, the embodiments encompass a distributed computing solution to use one or more isolated hosts to process the clustering steps in parallel. As such, in order to accomplish the distributed computing solution, the embodiments encompass any type of software framework 126 such as a HADOOP distributed file system, which is known to one of ordinary skill in the art. Because the clustering component 124 may be implemented in a distributed computing solution, the clustering component 124 may perform the clustering operations across a number of application servers 104. Alternatively, the clustering component 124 does not necessarily have to be implemented using a distributed computing solution, where the clustering logic may be implemented on the application server 104 associated with the brainstorming logic component 116, message service component 114, and the other components associated with the cloud brainstorming service.

In addition, the clustering component 124 may be pushed into the in-memory database system level. For example, as indicated above, the in-memory database systems 130 may have the capabilities of transactional and analytical processing. As such, the in-memory database stations 130 may include one or more processing units for carrying out such operations. Therefore, the embodiments encompass the situation where the clustering component 124 is located within the in-memory database systems 130, and the clustering results are provided to the participants via the message service component 114 in conjunction with the API 106.

After the clustering component 124 arranges the submitted ideas into the one or more clusters, the message server component 114 may provide the submitted ideas which are arranged into the one or more clusters over the network to the participants for display via a display screen that is common to each of the participants. Also, the clustering component 124 may store the cluster results in the in-memory database system 130. The details of the clustering operating are further detailed with respect to FIG. 5 of the disclosure.

According to one embodiment, in order to improve the scalability and availability of the application server 104, the node cluster 118 may be configured to balance the clustering operations throughout the number of application servers 104 when the clustering operating is implemented in a distributed solution. In particular, one application server 104 may include a cluster management node as a master application server. The other application servers 104 may be configured as slave servers, which may be centrally managed by the cluster management node. The cluster management node may dispatch the user requests to the appropriate application servers 104 based on configured algorithms such as round-robin, response-time, least-loaded, and/or weighted, for example. Also, the system 100 may include a load balancer 120 that may be configured to balance the loading across the number of application servers 104 according to methods that are well known to one of ordinary skill in the art.

FIG. 2 illustrates the brainstorming logic component 116 according to an embodiment. Referring to FIG. 2, the brainstorming logic component 116 may include a data collector 132, a duplication checker 134, a manual adjuster 136, a social share component 138, a summary generator 140, and an idea voting component 142.

The data collector 132 may be configured to collect the submitted ideas via one or more different communication channels from the devices 102 over the network. For example, as indicated, each member of the brainstorming session may submit his/her ideas via the idea submission page. As such, the message service component 114 may receive the plurality of ideas over the network from the users. The data collector 132 may collect the submitted ideas and store the ideas in the in-memory database system 130. In particular, the data collector 132 may store original submitted ideas and processed ideas in different tables in the in-memory database system 130. Further, the data collector 132 may store submission information associated with each of the submitted ideas in the in-memory database system 130 such as user information and time of submission. Because the in-memory database system 130 may already support a number of parallel sessions, the data collector 130 may directly store the submitted ideas and the submission information directly in the in-memory database system 130. Alternatively, the data collector 130 may utilize data collection techniques such as data synchronizations tools, data services, and/or extract, transform, and load (ETL) mechanisms.

The duplication checker 134 may be configured to detect duplicate ideas among the plurality of submitted ideas and delete the detected duplicate ideas. For example, in the brainstorming sessions, users may be encouraged to submit as many ideas as possible. As such, there may be a number of duplicate ideas, which do not have to be independently stored in the in-memory database system 130. As such, the duplication checker 134 may be configured to detect duplicate ideas, and delete the duplicate ideas such that duplicate ideas are not presented to the participants and/or stored in the in-memory database system 130. According to an embodiment, the duplication checker 134 may be configured to determine whether any synonyms exit for each word in each idea based on a dictionary stored in the in-memory database system 130. The duplication checker 134 may be configured to replace each word with an assigned word if a synonym exits for a corresponding word. Thereafter, the duplication checker 134 may calculate a similarity metric for each of the plurality of ideas, and detect a duplicate idea if two or more ideas have a similarity metric above a threshold value. The details of the duplication checker 134 are further illustrated in FIG. 4, which is explained later in the disclosure.

The manual adjuster 136 may be configured to receive adjustment information over the network, from a host (or possibly another participant) of the brainstorming session, and adjust the clusters based on the adjustment information including adding a new cluster, changing a name of the clusters, adjusting the ideas among the clusters, creating a new idea, and/or combining duplicate ideas. For example, upon reviewing the arrangement of the ideas into the clusters, a user may decide to change the name of one or more clusters, add a new cluster, create a new idea, or combine duplicate ideas (which were not detected by the duplication checker 134). In such a case, the manual adjuster 136 may receive the adjustment information reflecting the above-described functions, and adjust the clustering results accordingly. In other words, the user can change the idea-cluster relationship, add a new cluster, or move an idea into a different cluster. The manual adjustment may be marked in the in-memory database system 130 as one of the idea's attributes so that further automatic clustering/duplication check will not make any changes on the manual adjustment result.

The social share component 138 may be configured to analyze relationships and similarities between each topic and idea for all or most brainstorming sessions. For example, the in-memory database system 130 may be configured to store brainstorming topics, ideas, and results for a number of brainstorming sessions. In other words, the in-memory database 130 stores information for all the brainstorming sessions related to a certain enterprise. According to one aspect, a user of the cloud brainstorming session may enter a social share page, which may provide a plurality of topics and a plurality of ideas for each topic, and arrange similar topics into groups. Further, the user may be able to select a particular topic within the group, and the user is presented with the top ideas related to that particular topic (or all the ideas). The social share component 138 may use the same clustering mechanism to check the similarity between topics. As such, users can use this function to check whether there are similar ideas or topics which are already discussed by other teams before or after the brainstorming meeting, as well as browse the top ideas they are discussing.

The summary generator 140 may be configured to automatically generate a summary of the brainstorming session. For example, by using the cloud brainstorming service, the brainstorming session information is stored and managed in the in-memory database system 130. As such, the summary generator 140 may access this information such as the topics, ideas, cluster results, participant information, session information (e.g., date, period of time), voting results information, and generate a summary report that includes one or more of these types of information. Upon selection by the user, the summary generator 140 may generate a summary report, and provide the generated summary to the requested user. In one embodiment, the summary generator 140 may generate a portable document format (PDF) document or WORD version, and transmit the document via a linked email system. Also, the summary report may be included an email to the user. Alternatively, the summary report may be provided to the user on the user interface associated with the brainstorming session. In another embodiment, the summary generator 140 may be integrated with an internal portal associated with the company registered with the cloud brainstorming service. The summary itself may encompass virtually any type of format such as the list of top ideas, pie charts of ideas for each clusters, or any other type of arrangement having one or more the above-described brainstorming information.

The idea voting component 142 may be configured to receive voting information, over the network, from each of the members, and the message service component 114 may be configured to provide, over the network, voting results information to be displayed with the submitted ideas. For example, as indicated above, after the ideas are submitted to the cloud brainstorming service, the clustering component 124 arranges the submitted ideas into one or more clusters, and provides the arrangement of the ideas to each member of the brainstorming session. According to one embodiment, each participant of the brainstorming session may vote for the top ideas. As such, the idea voting component 142 may receive the voting information from each of the participants and rank the submitted ideas. Then, the message service component 114 may provide the voting results information over the network to be displayed with the arrangement of the submitted ideas.

FIG. 3 is a flowchart illustrating example operations of the cloud brainstorming service using the system 100 of FIG. 1 according to an embodiment. Although FIG. 3 is illustrated as a sequential, ordered listing of operations, it will be appreciated that some or all of the operations may occur in a different order, or in parallel, or iteratively, or may overlap in time.

A plurality of ideas may be received, over a network, from one or more users of devices, where the users represent members of a brainstorming session (302). For example, the message service component 114 may be configured to receive, over the network, from one or more users of the devices 102. In particular, when a user (the host) wishes to create a new brainstorming session, the message service component 114 may provide, over the network, a new brainstorming session template to the host of the brainstorming session. The new brainstorming session template may provide brainstorming settings for selection by the host. For example, the brainstorming settings may include the subject of the brainstorming session, the participants, the time period, a brief description of the brainstorming session, and one or more topics to be discussed in which ideas are solicited from the identified members. Thereafter, the message service component 114 may receive the brainstorming session settings via the new brainstorming session template, and then provide an idea submission page to the identified participants. For example, the idea submission page permits each participant to enter his/her ideas for each of the topics identified by the host in the new brainstorming session template. Then, the message service component 114 may receive, over the network, the plurality of ideas from the participants after the participants submits his/her ideas.

The plurality of ideas may be processed and stored in an in-memory database system (304). For example, the brainstorming logic component 116 may process the plurality of ideas and then store the processed plurality of ideas in the in-memory database system 130. In a further example, the data collector 132 may be configured to collect the submitted ideas via one or more different communication channels from the users of the devices 102. As indicated above, each member of the brainstorming session may submit their ideas via the idea submission page. As such, the message service component 114 may receive the plurality of ideas over the network from the users such as devices 102. The data collector 132 may collect the submitted ideas and store the ideas in the in-memory database system 130. Also, the system may process the plurality of ideas by using the duplication checker 134 that may be configured to detect duplicate ideas among the plurality of ideas and then delete the detected duplicate ideas. The deletion of duplicate ideas may include merging duplicate ideas into a single idea while retaining submitter information for each of the user who submitted duplicate ideas. According to an embodiment, the duplication checker 134 may be configured to determine whether any synonyms exits for each word in each idea based on a reference dictionary stored in the in-memory database system 130. The duplication checker 134 may be configured to replace each word with an assigned word if a synonym exits for a corresponding word. Thereafter, the duplication checker 134 may calculate a similarity metric for each of the plurality of ideas, and detect a duplicate idea if two or more ideas have a similarity metric above a threshold value.

A plurality of processed ideas may be received from the in-memory database, and the plurality of processed ideas may be arranged into one or more clusters, where each cluster is a group of similar ideas (306). For example, the clustering component 124 may be configured to retrieve the submitted ideas stored in the in-memory database system 130 and arrange the submitted ideas into one or more clusters, where each cluster is a group of similar ideas. The clustering component 124 may be configured to automatically arrange these ideas into one or more clusters or categories.

The plurality of processed ideas that are arranged into the one or more clusters may be provided, over the network, to the one or more users for display (308). For example, the message service component 114 may provide the ideas that are arranged into the clusters, over the network, to the one or more users for display. Further, according to another embodiment, a user may wish to adjust the results of the clustering operation. In such a case, the manual adjuster 136 may be configured to receive adjustment information over the network, from a host of the brainstorming session, and adjust the clusters based on the adjustment information including adding a new cluster, changing a name of the clusters, adjusting the ideas among the clusters, creating a new idea, and/or combining duplicate ideas. For example, upon reviewing the arrangement of the ideas into the clusters, the host may decide to change the name of one or more clusters, add a new cluster, create a new idea, or combine duplicate ideas. In such a case, the manual adjuster 136 may receive the adjustment information reflecting the above-described functions, and adjust the clustering results accordingly. In other words, the user can change the idea-cluster relationship, add a new cluster, or move an idea into a different cluster.

In addition, the host of the brainstorming session may permit voting on the best ideas within each topic. As such, the idea voting component 142 may be configured to receive voting information, over the network, from each of the members, and the message service component 114 may be configured to provide, over the network, voting results information to be displayed with the submitted ideas. For example, as indicated above, after the ideas are submitted to the cloud brainstorming service, the clustering component 124 arranges the submitted ideas into one or more clusters, and provides the arrangement of the ideas to each member of the brainstorming session. According to one embodiment, each participant of the brainstorming session may vote for the top ideas. As such, the idea voting component 142 may receive the voting information from each of the participants and rank the submitted ideas. Then, the message service component 114 may provide the voting results information over the network to be displayed with the arrangement of the submitted ideas.

Also, a user may wish to view a summary of the brainstorming session. As such, the summary generator 140 may be configured to automatically generate a summary of the brainstorming session. For example, by using the cloud brainstorming service, the brainstorming session information is stored and managed in the in-memory database system 130. As such, the summary generator 140 may access this information such as the topics, ideas, cluster results, participant information, session information (e.g., date, period of time), and generate a summary report. Upon selection by the user, the summary generator 140 may generate a summary report, and provide the generated summary to the requested user.

FIG. 4 is a flowchart illustrating example operations of the duplicate checker 134 according to an embodiment. Although FIG. 4 is illustrated as a sequential, ordered listing of operations, it will be appreciated that some or all of the operations may occur in a different order, or in parallel, or iteratively, or may overlap in time.

Synonyms may be replaced (402). For example, the duplication checker 134 may be configured to determine whether any synonyms exit for each in each idea based on a reference dictionary stored in the in-memory database system 130. In particular, the in-memory database system 130 may store a relatively large reference dictionary. The duplication checker 134 may be configured to scan each word in each idea in order to check if any synonyms exit in the database. If synonyms are detected, the duplication checker 134 may be configured to replace the word with an assigned word. For example, the term “street”, “St.” or “road” may be all replaced by the term “street.”

Similarities may be calculated (404). For example, the duplication checker 134 may calculate a similarity metric for each of the plurality of ideas, and detect a duplicate idea if two or more ideas have a similarity metric above a threshold value. In particular, the duplication checker 134 may utilize a similarity algorithm to calculate the similarities between all submitted ideas. The similarity algorithm may be the Levenshtein Distance algorithm, the Longest Common Substring (LCS) algorithm, or a combination of these algorithms. Basically, the duplication checker 134 calculates a similarity metric for each of the submitted ideas using the similarity algorithm, and then based on the similarity metric, the duplication checker 134 determines whether any of the ideas are duplicates based on the similarity metric being equal to or above a threshold value.

Duplicate ideas may be merged (406). For example, once duplicate ideas are detected, the duplication checker 134 may be configured to delete the duplicate ideas. In one embodiment, the duplication checker 134 may be configured to merge the duplicate ideas into a single idea while retaining submitter information for each of the participants who submitted the duplicate ideas. For example, the duplication checker 134 may be configured to collect the submitters' information related to the duplicate ideas from the in-memory database system 130, and then assign the submitter's information to the leading idea. Subsequently, the duplication checker 134 may be configured to remove all duplicates ideas except the leading ideas.

FIG. 5 is a flowchart illustrating example operations of the clustering component 124 according to an embodiment. Although FIG. 5 is illustrated as a sequential, ordered listing of operations, it will be appreciated that some or all of the operations may occur in a different order, or in parallel, or iteratively, or may overlap in time.

The submitted ideas may be pre-processed (502). For example, the clustering component 124 may retrieve the de-duplicated ideas from the in-memory database system 130 by applying one or more specific filters to the ideas. At this point, each idea is a text string, and the clustering component 124 may parse the de-duplicated ideas using a word separating process in order to generate word sets.

Stop words may be removed (504). For example, the clustering component 124 may be configured to remove stop words from each word set. Stop words may be referred to as filter words such as “is”, “a”, “the”, etc., which are essentially meaningless and not relatively helpful for the clustering operation.

Bag of words may be created (506). For example, the clustering component 124 may be configured to extract words from the word sets. In particular, the words in the word sets are still in the original sequence before creating the bag of words. Thus, the clustering component 124 may be configured to analyse and extract the words from the word sets and remove the sequence. The result of performing such an analysis and extraction are referred to as a bag of words model. The clustering component 124 may utilize an SCPCD algorithm, or any other known technique for creating a bag words from a set of word sets.

Feature words may be selected from the bag of words (508). For example, the clustering component 124 may be configured to select one or more feature words from the extracted words (e.g., the bag of words). Feature words may be an important attribute for a bag of words. According to one embodiment, the clustering component 124 may utilize any type of DF algorithm in order to carry out the feature words selection.

VSMs models may be created (510). For example, the clustering component 124 may be configured to transform text data of the selected feature words into a plurality of vector space models (VSMs). In particular, the clustering component 124 may be configured to model the feature words using the VSMSs for text analytics. A python based procedure may be instituted to loop the processed word sets and transform them into the VSM model.

A K-means calculation may be performed (512). For example, the clustering component 124 may be configured to arrange the plurality of processed ideas into one or more clusters based on the plurality of VSMs. One approach is the K-means simulator. If the clustering component 124 utilizes the K-means simulator, the clustering component 124 may first calculate the center point of all automatically generated clusters. Then, the clustering component 124 may calculate the distance from each VSM to its respective center point. As a result, the clustering component 124 may assign the idea corresponding to the VSM that is closest to the cluster.

FIGS. 6-12 illustrate various screens shots of the cloud brainstorming service according to an embodiment. For example, FIG. 6 illustrates a home page 600 providing an overview of all existing brainstorming sessions. For example, the home page 600 may be a home page for a particular user of the cloud brainstorming service. As show in FIG. 6, the home page 600 provides a plurality of existing brainstorming sessions 610, where each brainstorming session 610 may include one or more topics 615. With respect to each topic, the home page 600 may indicate a status of the brainstorming session—new, idea, finish, or vote. The term “new” may indicate that the topic is relatively new such as topic 615-1 under brainstorming session 610-1. In other words, the term “new” may indicate that a particular topic has recently been presented for the submission of ideas. The term “idea” may indicate that the user may have already viewed the topic, but still needs to submit his/her ideas such as topic 615-3 under brainstorming session 610-2. The term “finish” may indicate that the user has submitted his/her ideas as well as the voting information that indicates the user's preferred rank of ideas. The term “vote” may indicate that the user still must submit his/her voting information related to the top such as topic 615-2 under brainstorming session 610-2, for example.

FIG. 7 illustrates a new brainstorming session template 700 according to an embodiment. For example, when a user (the host) wishes to create a new brainstorming session, the message service component 114 may provide, over the network, the new brainstorming session template 700 to the host of the brainstorming session. The new brainstorming session template 700 may provide brainstorming settings for selection by the host. For example, the brainstorming settings may include the subject 710 of the brainstorming session, the participants 715, the time period 720, a brief description 725 of the brainstorming session, and one or more topics 730 to be discussed in which ideas are solicited from the identified members 715. Upon completing of the brainstorming session template 700, the host may select the send selection, which the message service component 114 may receive, over the network, the selected brainstorming settings. In response, the message service component 114 may provide, over the network, an idea submission page to each of the members 715, as further shown in FIG. 8.

FIG. 8 illustrates an idea submission page 800 according to an embodiment. In the example of FIG. 8, the idea submission page 800 relates to topic 730-2. In this case, the user has entered ideas 810 related to this topic. Upon completing the number of ideas the user wishes to submit, the user may select the submit selection in order to send the ideas to the cloud brainstorming service. As such, the message service component 114 may be configured to receive the ideas related to this topic, over the network, from the user. The other members of this brainstorming session would submit their ideas in the same manner. As a result, the message service component 114 receives a plurality of ideas, over the network, from the members of the brainstorming session.

When all the ideas are submitted, the duplication checker 134 may detect duplicate ideas and merge the duplicate ideas while retraining the submitter information, as previously described above. Next, the clustering component 124 may arrange the plurality of de-duplicated ideas into one or more clusters in the manner previously described. As a result, the message service component 114 may provide, over the network, the plurality of de-duplicated ideas that are arranged into the one or more clusters to the members for display.

FIG. 9 illustrates a screenshot 900 providing the cluster results according to an embodiment. For example, the screenshot 900 provides the arrangement of the plurality of ideas into the clusters such as the first cluster 910-1 (e.g., communication), the second cluster 910-2 (e.g., facility 910-2) and the third cluster 910-3 (e.g., miscellaneous). The term “new” indicates that an idea has recently been received. Also, the screen shot 900 provides a user control 915 for manually adjusting the number of clusters. For example, by operating the user control 915, the user can define the quantity of clusters, and the clustering component 124 will re-clusters the ideas automatically. Also, the user can manually modify the cluster result such as creating a new cluster, changing the cluster of a particular idea (e.g., move an idea from one cluster and place it into another cluster), create a new idea, and/or combine duplicate ideas. In one embodiment, the manual adjuster 136 may be configured to receive adjustment information over the network, from a host of the brainstorming session, and adjust the clusters based on the adjustment information including adding a new cluster, changing a name of the clusters, adjusting the ideas among the clusters, creating a new idea, and/or combining duplicate ideas.

With respect to voting mechanism, the host can specify the quantity for each participant to vote, and, when a user completes his/her turn, the user may be able to see the overall voting status, as provided in FIG. 10. FIG. 10 illustrates a screenshot 1000 depicting the voting results according to an embodiment. The voting results may be provided in real-time or near real-time. For example, the idea voting component 142 may be configured to receive voting information, over the network, from each of the members, and the message service component 114 may be configured to provide, over the network, voting results information to be displayed with the submitted ideas. As shown in FIG. 10, the screenshot 1000 includes information indicating the amount of votes casts for each idea.

FIG. 11 illustrates a screenshot 1100 depicting the social share aspect according to an embodiment. For example, the social share component 138 may be configured to analyze relationships and similarities between each topic and idea for all the topics and ideas submitted through the cloud brainstorming service. For example, the in-memory database system 130 may be configured to store brainstorming topics, ideas, and results for a number of brainstorming sessions. In other words, the in-memory database 130 stores information for all the brainstorming sessions related to a certain enterprise. According to one aspect, a user of the cloud brainstorming session may enter a social share page as illustrated in FIG. 1100, which may provide a plurality of topics and a plurality of ideas for each topic. As shown in FIG. 11, the topics are arranged into groups, where each group includes a set of similar topics. For instance, one group of topics relates to gifts and another group of topics relates to baby names. Although only four groups of topics are illustrated in FIG. 11, the embodiments encompass any number of groups. The social share component 138 may use the same clustering mechanism to check the similarity between topics. As such, users can use this function to check whether there are similar topics which are already discussed by other teams before or after the brainstorming meeting, as well as browse the top ideas they are discussing. For example, the user may be able to drill-down into the ideas for each of the topics, as shown in FIG. 12.

FIG. 12 illustrates a screenshot 1200 depicting ideas in a topic group according to an embodiment. For example, after the user selects a group, the social share component 138 may provide the top five ideas for the topic group, and/or each topic. As shown on the right side of FIG. 12, the top five ideas are presented for the first two topics (e.g., gift for teacher, birthday gift) along with information indicating the ranking of the ideas (e.g., 1^(st), 2^(nd), 3^(rd)). The user may adjust the screenshot 1200 by scrolling in order to review the other top ideas for the other two topics. Although the top five ideas are presented in the example of FIG. 12, the embodiments encompass any number of ideas to be displayed within the social sharing screenshot 1200. As a result, users are able to share their brainstorming session with other users, and also browse other brainstorming sessions. Also, the social share component 138 may recognize the text of all brainstorming topics, group similar topics together, and generate the top N most important ideas of these groups such that the users are able to understand the overall discussion results for his/her interested topics.

For example, as indicated above, after the ideas are submitted to the cloud brainstorming service, the clustering component 124 arranges the submitted ideas into one or more clusters, and provides the arrangement of the ideas to each member of the brainstorming session. According to one embodiment, each participant of the brainstorming session may vote for the top ideas. As such, the idea voting component 142 may receive the voting information from each of the participants and rank the submitted ideas. Then, the message service component 114 may provide the voting results information over the network to be displayed with the arrangement of the submitted ideas.
